We used the Scribbly Christmas stamp set from Tim Holtz to create a few projects during our Holiday Workshop. We inked the tree stamps with Tim Holtz Distress Markers, stamped it onto watercolor paper, and used a damp brush to tap some moisture onto the images. This gave the trees a softer, watercolored look.
Here is the tree added to a burlap canvas from Tim Holtz.
Here's the same technique, added to a card. Quick and easy!
